new and useful Improvements Machines for Pressing Clay or Powdered Substances, and forming the same into cakes, blocks, or bricks, which improvements are fully set forth in the following specification, reference being had to the accompanying drawings. v This .invention consists in the employment,

' iny a machine f'or pressinglclay or powdered substances' into cakes, blocks, or bricks, of a hopper to contain the material, a groove or grooves in which the substance is pressed, a plunger and counter-plunger to work therein and press the material into cakes, a slide to raise said cakes from the grooves, and an endless carrie-r to remove. the cakes* as fast as formed, the whole being combined with suitable mechanism to form an operative machine, in the'manner hereinafter more fully set forth. Figure l represents a central vertical longitudinal section of a machine embodyingimy improvements. Fig. 2 is a top view of the same. Fig. 3 is a vertical cross-section through the hopper. Fig. 4 is a detached top view of the plungers, counter plungers, and slide, shown in position for the removallof the cakes from the grooves by the slides. Fig. 5 is a detached end view of the plungers, slide, and cam for moving the plunger, and a rear view of the operating-lever.

A represents the hopper of the machine resting upon a cross-plate, B, secured horizontally upon the frame of the machine, which consists of side pieces O C, connected by` cross-pieces D D at each end, in which crosspieces the main or driving shaft E has its bearings F F. On the inner sides of the upper portion of the frame are cast or secured V-shaped horizontal ways G G, on which is xed a cross-piece, B, and on which slides H and I freely move. Close to the left of said.

cross-piece is a vertical slide, J, which-works up and down upon suitable guides or ways on the inner sides of the frame. Over the slide I are arranged two rollers, which carry an endless band, K, one of which rollers is located close and parallel to the slide J, in suitable bearings on the upper part of the frame C C,

and theother in bearings on the end'offsaid ings at fa considerable distance from the ma-A chine, to allow the finished cakes on the end- .less band `to harden and dry sufficiently for handljn g before removal from the band. Near theslide J are two standards, attachedto and forming part of the frame .0, each of which has two bearings to receive theshafts A.L and O. Attached to said shaft is a flap, L', which extends down to the top surface of the band- K, or nearly so, and an arm or projection,

Around one end. of this shaft is a spiral spring, N, one end of which is fastened-to the shaft, and the other end to the frame 0;. At

the right of, and parallel to, the shaft L is the other shaft, O, whichhas upon it a wiper, P, to operate upon the arm Mas lit-revclves, and thus give ,the flap L a vibratory motion to- Iward the apron or band K. After the wiper P has passed the arm M, the-spiral spring N causes the flap to return to lits original posi.-

I tion beyond the slide J, and rest against a stop on the frame C. y

To propel theshaftO and endless band K a separate counter -,shaft,v Q, is employed, arT ranged in suitable bearings on one side'of the main frame, which shaft has a gear or pulley to receive motion from a gear or pulley, R, upon the main shaft E, a bevel-gear to transmit motion to the shaft O by means of a vertical shaft and bevel-gears, and a band-pulley to impart motion by means of a band to the roller carrying the endless band or carrier K.`

If preferred, the shaft O may be driven by band-pulleys, in the same way as the roller operating the band K.

In the cross-piece B are one or more grooves, S S S, corresponding in number and crosssec tion with the plungers T T T used, and the cakes, bricks, or blocks to be formed, which.

grooves are arranged under the dischargeopening of the hopper and in line with the plungers, so that the latter will work therein. Said plungers T T T are secured in grooves in the slide H bymeans of screws passingthrough slots, so that the plungers may be adjusted longitudinally, as desired.

The slide and plungers are reciprocated by means of' a cam, U, and vibrating lever V, the

passing through latter having trunnions workingin the bearings formed` in` thesides of the frame C G, a friction-wheel on its lower end, and aslot in its upper arm, through which works a pin eyes on the slide H. At'V is a spring acting on lever V.

Ou the slide I are secured counter-plungers W W W, to which motion is imparted in the same way as the plungers S S S by means of the lever V, cam I', and Vspring V but the time and amount of motion are varied, and

the cams are therefore varied also.

The cam U is of such shape as to give one motion to compress the substance and form the cake, a secondary motion to push forward and discharge the cake from the grooves, and a third to rapidly withdraw from under the hopper-openin g and return to its origin al position. The cam Il has only a forward :motion to press the cake, and a backward one to allow it to be discharged.

The slide J is operated by a cam, X., pressing against a friction-roller on the bottom of said slide; and a spring or springs, Z, may be eniployedlto keep the roller in contact with the cam, should not the weightof the slide be found suicient.

The operation of the machine may be described as follows: The hopper is rst charged with the substance to be operated on, and, if necessary, a weight added to force the material into the grooves. Motion is then given to the machine, by which means the plungers T T T are drawn back to allow the grooves to fill from the hopper, the slide J descends belowthe grooves S S S, and then both sets of pliuigers are pushed toward each other, to press the material into cakes. The plungers W remain stationary long enough to allow the plungers T to produce sufficient pressure on the material, and then theirmotion is reversed sufficiently to allow the plungers T to force the cakes over the slide J and yet retain the pressure on said cakes. i The slide J now rises, and, being of the precise thickness of the space between the two sets of .plungers, takes the cakes from between them, andraises said cakes to the level of the" upper surface of the band K. ,The plungers T return to their original position, to allow of the filling of the grooves for the next operation. As soon as the slide J has risen to its full height, the motion of the flap L', caused by the wiper l? on the arm M, pushes the cakes off the top of the slide over a guide, y, between the slide and apron or band K onto said band K, which carries it away.

In' operating upon some substances, themachine is so arranged as to have the slides I and H arrangedvertically and the slide J horizontally, or nearly so. In such case the apron or 'band K is still arranged horizontally, and the cake is delivered by the slide `J directly` upon the band K, and the ilap L is in such case dispensed with. y

Instead of the cams upon the main shaft, cranks or other suitable moving devices may be used to operate the slides.

What I claim as my invention is- 1. The combination of the plungers T, ,the grooves S, counter-plungers W, slide J, and hopper A, to form and press 4the cake, substantially as herein set forth.

v 2. The combination of the gers T, grooves S, countenplungers W, slide J, guide y, and endless band K, substantially`- as described and set forth.

3. The combination of the hopper A, plun-` gers T, grooves S, counter-plimgers W, slide y J, liap L', and vendless Aband K, substantially as herein shown and described.

4. Thecombination of the hopper A, plungers T, the grooves S, counter -plungers W, slide J, iiap Il', band K, slides I H,cams U X I, and levers V V, substantially as described.

In witness whereof I hereunto set my hand.
